A bombing recently took place at Greenpoint's Transmitter Park, but the aftermath was a swath of soft and fluffy yarn. A delicate white doily with a sky-blue center materialized around one of the North Brooklyn park's banisters this weekend, attracting the curiosity of passersby. We've seen other yarnbombings in Brooklyn, but the understated style of this new piece seems to be the work of a newcomer and so far, no one has come forward to claim the art as their own.
